SPECIFICATION forming part of Letters Patent No. (527,198, dated October 9, 1,894.

l Application tiled November 15,1 893.` Serial No. 490,971. `(No InodeLl To all whom it may concern:

Be it known that I, WILLIAM F. DIMMICK, of Decatur, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Trusses for the Joints of Railway-Rails, of `which the following is a specilication. j

This invention is designed to provide substantial supports for the joints of railway rails, and it is embodied in the details of construction andcombinations of parts hereinafter set forth and claimed. t

In the drawings forming part of this speciiication Figure 'l is a perspective representation of a truss in proper relation to the rails and ties, but not secured in position. Fig. 2 is a perspective representation of the bridge plate. Fig. 3 shows the truss member in perspective. Fig. 4 is a side elevation of a section of track, with my device applied to the joint of the rails.

The rails are shown at l, the joint thereof at 2, and the ties at 4. At 3 is shown one of a pair of ordinary angle bars,such bar being slotted, as seen at 13, to admit the spikes used to secure the rails to the ties. Abridge plate comprising the seat portions, the downwardly converging portions 6 and the horizontal portion 7, has holes, as l2, which coincide with the slots of the angle bars, and is preferably provided with slots, as 1l, at the junction of the converging sides with the horizontal portion. The bridge plate is placed under the rails with the seat portions 5 resting on the ties, and the center of part 7 under the joint of therails; and it is secured to the j ties and to the angle bars, in a manner to prezontal portion of the bridge plate. The sides,

which are designated by characters 9, are

yield only by contracting longitudinally, t. e.

by bringing the seat portions nearer together,

and this is prevented by the bars and the spikes. i

Having thus described `my invention, I claim as new and desire to secure by Letters Patentn l. A truss for the joints of railway rails, comprising a bridge plate composed of seat portions, downwardly converging portions and ahorizontal portion connecting the converging portions, slotsat the intersections of the converging portions with the lower horizontalportions, and an A-shaped truss having studs adapted to engage the slots of the bridge plate, substantially as set forth.

2. In joint trusses, the combination of the bridge plate comprising the parts 5, G and 7 and slotted, or perforated, at 11 and at 12, the truss comprising part-s 8, 9 and 10, the angle bars having the slots 13, and spikes as 14 to secure the angle'bars and the bridge plate together, while connecting both with the ties, substantially as set forth.

In testimony whereof I sign my naine in the presence of two subscribing witnesses.

WILLIAM F. DIMMICK.
